y and power factor distinctive features, starting from the late 1970s, the permanent mag synchronous motor to get wide attention. With the development of highperformance permanent mag materials and declining prices, the application of permanent mag motor is more extensive. Especially in recent years, with the advances in the rapid development of permanent mag materials and power electronics and control technologies, permanent mag synchronous motor will increasingly replace traditional motor, the prospects are very optimistic, permanent mag motor drive controller the design has bee a hot topic of the motor areas of research, thus it is very significant to the study of permanent mag synchronous motor. This article first a brief introduction to the structure of the permanent mag synchronous motor, the performance, then a more prehensive description of the development status and trends of the permanent mag synchronous motor and its related technologies, and finally about several permanent mag synchronous motor control system monly used in control strategies. In the analysis of permanent mag synchronous motor mathematical model based on the help of Matlab39。 同時(shí)本文 在分析永磁同步電機(jī)數(shù)學(xué)模型的基礎(chǔ)上 ,借助于 Matlab強(qiáng)大的仿真建模能力 , 在 Matlab/Simulink中建立了 PMSM 控制系統(tǒng)的仿真模型 ,為 PMSM 控 制系統(tǒng)的分析與設(shè)計(jì)提供了有效的手段和工具。尤其是近年來,隨著永磁材料的迅速發(fā)展和電力電子和控制技術(shù) 的進(jìn)步,永磁同步電機(jī)將越來越多地替代傳統(tǒng)電機(jī),應(yīng)用前景非常的樂觀, 永磁電機(jī)及其驅(qū)動控制器設(shè)計(jì)也成了電機(jī)領(lǐng)域研究的熱點(diǎn)課題, 因而對永磁同步電機(jī)的研究是非常有意義的。永磁同步電機(jī)控制系統(tǒng)設(shè)計(jì)與仿真 永磁同步電機(jī)控制系統(tǒng)設(shè)計(jì)與仿真 目 錄 摘 要 ..................................................................................................................................
